30 * \brief A water infiltration problem with a low-permeability lens
31 * embedded into a high-permeability domain which uses the
32 * Richards model.
33 *
34 * The domain is box shaped. Left and right boundaries are Dirichlet
35 * boundaries with fixed water pressure (fixed Saturation \f$S_w = 0\f$),
36 * bottom boundary is closed (Neumann 0 boundary), the top boundary
37 * (Neumann 0 boundary) is also closed except for infiltration
38 * section, where water is infiltrating into an initially unsaturated
39 * porous medium. This problem is very similar to the LensProblem
40 * which uses the TwoPBoxModel, with the main difference being that
41 * the domain is initially fully saturated by gas instead of water and
42 * water instead of a %DNAPL infiltrates from the top.
43 *
44 * This problem uses the \ref RichardsModel
